If, for instance, a child makes a loud noise and sets off the warning beeps the dog now starts barking and runs to the front windows to the discover what needs to be barked at

even someone knocking on a door in a movie.. he completely ignores most noises now.

Also goes off from loud noises, whistles, etc

It seems to work I the leads are a bit big so you may not want to use it on short hair dogs.
